McMullin was also a children's ministry volunteer at Sequoyah United Methodist Church. Leaders at the church said he has been suspended while the investigation is pending.

Fayetteville Police Chief Greg Tabor said his department was helped by U.S. Postal Service inspectors in obtaining a search warrant for a home on East Margaret Place. Officers said child porn was playing on his computer monitor when they showed up to arrest him.

Investigators said the postal inspectors had worked a case in which several DVDs containing child pornography were mailed to the residence.
